SHAVING BRUSH.

Application filed January 25, 1923/ Serial No. 614,799.

T 0 all whom it may concern" Be it known that I, DUNCAN MAOKENZIEANDERSON, a subject of the King of Great Britain, and resident ofToronto, Province of Ontario, Dominion of Canada, have invented certainnew and useful Improvements in Shaving Brushes, of which the followingis a specification.

My invention is directed to' shaving brushes of the class used forlathering the face before or during shaving; and my improvements aredirected particularly to means whereby the bundles of bristles assembledin the brush may be separated from each other and opened out, so thatthey may be thoroughly washed and cleansed toremove accumulations oflather, soap, hair, particles of cuticle, and the like, which accumulatewithin the brush during use; the brush also being so constructed that itmay be thoroughly sterilized, as by boiling, without injurious effect onits parts.

In the drawings, Fig. 1 is an elevation of my improvedbrush; Fig. 2 is avertical sectional view of the same; Fig. 3'is a cross sectional viewtaken on the line 3-3 of Fig. 1, looking down; Fig. 4 is a crosssectional view on an enlarged scale, taken as on the line H of Fig. 1;Fig. 5 is a view showing the bristle holders spread out radially fromtheir central support to permit cleansing; and Fig. 6 is a side view onan enlarged scale, and Fig. 7 is a vertical sectional view, also on anenlarged scale, of one of the bristle holders.

Similar parts are designated by similar reference numerals in all thefigures.

The body 1 of the brush is preferably formed of light non-corrodiblemetal. It consists essentially of a tube having a central bore 2,flaring toward one end of the handle; the handle being provided with acap 3 adapted to seat itself over and close the other end of the handle.

Through a radially slotted. disk 4, which may be made of two pieces witha pivot receiving groove between them, is passed a shank 5, having acollar 6 below the disk,

and being threaded above the disk to receive a keeper nut 7, the shankbeing also threaded into the cap 3 so that when the cap is screwed downon the shank, the disk 4 fits snugly into the tapered bore of the handleand the cap and disk are both held firmly in proper position. The otherend of the shank is prolonged and is provided with an enlargement 8,which serves to fill the space between the series of bristle holders 9,9, which are held pivotally in the radial slots of the disk 4, as by apivot wire 10, or other suitable means.

In these bristle holders 9, 9, are mounted the bristles 11, 11,preferably by being looped around a keeper wire as 12, the sides of theholder being then closed together and secured to each other as bysoldering, so

and cannot drop out of the holder, unless they are broken free from thekeeper wire.

When the bristle holders are swung into their bunched position, as shownin Figs. 1, 2, 3 and 4, spaces are left between them which are notfilled by the bodies of the holders. These spaces are preferably closedby suitable elements such as 13, 13, attached laterally to the bristleholders, and adapted with them, and the enlargement 8, to snugly closethe end of the handle 1 into which the brush is inserted.

WVhen, therefore, the brush is assembled, as shown in Figs. 1 and 2, oneend of the handle will be securely closed by the cap 3, and the otherend will be closed by the enlargemen't 8, bristle holders 9, 9 and theirextensions 13, 13, so as practically to exclude lather and foreignsubstances from the interior of the brush handle. The brush, when soassembled, can be used like an ordinary shaving brush.

When it is desired to cleanse the brush, the cap 3 is screwed ofl, andthe shank 5, carrying with it the bristle holders, is pushed out of thetapered bore of the handle. The bristle holders may then be spread outlaterally, as illustrated in Fig. 5, and subjected to a thorough washingand cleaning, and then readily dried of free moisture by the use of atowel. For it will be seen that when spread out, the bristle holders mayrest conveniently upon a towel held in the hand, while the upper sidesare wi ed and dried, the holders and their attac ed parts being reversedin position and moved about so that all their surfaces can be reached inthe cleaning and drying operations.

Obviously the interior of the handle may be thoroughly cleansed; and thebrush, when disassembled, may be optionally subjected to heat or othersterilizing influences.

By the use of my invention I am enabled to eliminate the danger ofcontamination that the bristles are securely-held in place due to theaccumulation of germ carrying matter within the body of the brush; and.to provide the user with a brush, which can, with ordinary care, bekept in a thoroughly sanitary condition.

The detachable character of the brush elements makes my devicepeculiarly adapted for use in barber shops, where the brush can bethoroughly cleansed and sterilized, as by passing it through boilingwater, after each time it is used, a number of brush elements beingusable with a single handle if desired, so that a clean brush elementmay be inserted without delay in a handle, while the brush element whichhas been used is being cleansed and prepared for further use.

It will be understood by those familiar with the art that I haveillustrated and described a preferred but not an exclusive embodiment ofmy invention; for details of construction may be modified, as by the useof mechanical equivalents and the like, without departing from thespirit of my invention as described and claimed.

I wish it to be understood also that while I have spoken particularly ofthe adaptability of my improvements to a shaving brush; I have referredto the shaving brush in the sense of it being a typical article. For itis obvious that brushes so constructed may be used for other toiletpurposes, or for applying paints, varnishes, or the. like, where it isdesired to remove accumulations of matter from the brush after it hasbeen used and to thoroughly cleanse the brush.

' Having thus described my invention, what I claim and desire to secureby Letters Patent. of the United States is 4 1. The combination, in abrush, ofia handle, a carrier, a plurality of bristle holders eachmovably secured at one end to the carrier and provided at its other endwith a bunch of bristles projectingin line with the body of the holder,a shank arranged centrally through the carrier and provided with a freeend for the bodies of the holders to abut against, and meanson thehandle 00- operating with said shank fordetachably attaching the carrierto the handle with the bristle holders parallel with each other.

2. The combination, in a shaving brush, of a hollow handle, a carrier, aplurality of unitary groups of bristles pivoted in radial relation tothe carrier, and means for detachably securing the carrier within thehandle and thereby assembling the bristle groups in parallel as a brushunit.

3. The combination,.in a shaving brush, of-

a hollow handle, a unitary brush carrier, a plurality of independentunitary groups of bristles carried thereby in relatively movablerelation to each other and means for securing the carrier within thehandle and thereby assembling the bristle groups in fixed but releasableoperative position as a brush unit.

4;. The combination, in a shaving brush, of a hollow handle having atapered bore, a carrier, a plurality of unitary groups of bristlescarried thereby in relatively moveable relation to each other, means forsecur ing' the carrier within the tapered bore of the handle and therebyassembling the bristle groups in fixed but releasable operative positionas a brush unit.

tachably securing the carrier within the handle, a plurality ofbristleigroup holders carried by a carrier, means for assembling theholders in parallel within the handle, and means for closing the spacesbetween the holders.
